The best Byzantine chants in my opinion are the following:
Mount Athos, Simonopetra monastery:
Agni Parthene (Αγνή Παρθένε

. The self-titled hymn by St. Nectary and Aineite ton Kyrion (track 3!) are simply amazing.
Psaltirion Terpnon (Ψαλτήριον Τερπνόν

Theia Leitourgia (Θεία Λειτουργία, Τhe Divine Liturgy)
and
Mount Athos, Vatopedi monastery:
Hymns of Holy Monday (Ύμνοι της Μ. Δευτέρας

. I think I always have shivers down my spine every time I listen to "Erchomenos o Kyrios pros to pathos", which is Christ talking to his disciples before the crucifixion and comforting them. The words are simply beautiful but just the concept and that music is what does it for me. Goes slowly and somberly, then rises in emotion when Christ says that they will nail me to the cross, give me to sinful hands but have courage, in three days I will rise to the rejoice of the faithful and for eternal life.
I dont know, I find it simply unbelievable, the perfect music for the perfect words, that unique combination of sorrow and love and joy.
Other amazing hyms are "Ton Nymfona Sou Vlepo" with its beautiful words (I see your bridal chamber adorned, O my Savior, and I have no wedding garment that I may enter therein; O giver of Light, make radiant the vesture of my soul and save me), or "Idou, o Nymfios Erchete".
Holy Pascha (Άγιον Πάσχα

. Now this is the pinnacle. The words coupled with the joyful yet still solemn style of the byzantine choir are the best way to convey the happiness these monks feel on the Feast of Feasts. There is no single standpoint, although "Christos Anesti" and "Pascha Ieron" are sure to hit home
finally, I really like the recordings by Aggelopoulos and his choir, the Divine Liturgy, the Akathist Hymn to the Theotokos etc... He was the one who trained the Vatopedi monastery monks by the way.
I too prefer male choirs, these recordings are the best represenations imo of my preferences.
I'm sure I saw links around in this thread to some samples of them.
I love Byzantine music. It was what really got me going in the first place and I only started aesthetically. But once you understand the genuinity of the artists and what they are really doing (ie worshipping Christ) then it's a whole other story!
Christos Anesti!
